PHP error category

Exceptions

Thrown and uncaught exceptions.

Exceptions errors arise when thrown and uncaught exceptions affect an executing PHP application or its supporting service. Use the exact signature and runtime context to narrow the cause before changing configuration.

The guides in this category separate code defects from environment differences, show focused diagnostics, and favor site-scoped corrections that preserve unrelated applications.
